Title: Ionization chamber with electron source
Inventor: DORING HANS-RUDIGER
IPC: G01N27/64
Filed: 2000-07-11
Abstract: Ionization chamber, especially for an ion mobility spectrometer, with a non-radioactive electron source. The chamber consists of two compartments, of which one is evacuated and contains an electron source, and the other represents the reaction chamber of the IMS. In the evacuated compartment, X--ray quanta are produced in an anode by electron bombardment and these X-ray quanta can penetrate a partition between the two compartments. The partition between the two compartments is impermeable to electrons from the source and to gas molecules. In one or several conversion layers within the reaction compartment, X-ray quanta are converted to quanta of a lower energy and/or photoelectrons that can ionize the air constituents at a high level of efficiency.
Patent CA-2316892-A1 (CA)
Inventor: HAGER JAMES W
IPC: H01J49/42
Filed: 1998-05-28
Abstract: On décrit un procédé de fonctionnement d'un spectromètre de masse à barres à l'intérieur duquel on introduit des ions précurseurs et un gaz de collision. Une tension aux radiofréquences suffisante et une quantité faible mais suffisante de tension de résolution à courant continu sont appliquées sur les barres pour activer le spectromètre de masse à proximité de la limite .beta. = 0 pour les ions précurseurs, d'où une dissociation activée en limite d'au moins quelques-uns des ions précurseurs pour produire des ions-fragments. Les ions-fragments et d'éventuels ions précurseurs résiduels sont dirigés à l'intérieur d'un spectromètre de masse subséquent pour détection et analyse. Le procédé permet une résolution en masse modérée de l'ion précurseur qui peut être utilisée pour obtenir des informations SM/SM à partir d'un seul quadrupôle et des informations SM?3¿ à partir d'un triple quadrupôle. Lorsque le CC est balayé sur une partie seulement du spectre, des informations de fragmentation peuvent être obtenues à l'intérieur d'une zone prédéterminée du spectre, le reste du spectre affichant des éléments de spectre d'ions précurseurs non fragmentés. Le procédé peut s'utiliser également dans la cellule de collision d'un spectromètre de masse à triple quadrupôle pour obtenir des cellules de collision plus courtes pour un coût réduit. Le procédé peut s'utiliser en outre pour réaliser une dissociation d'ions précurseurs fortement agglomérés du type généralement obtenu par des techniques d'électro-pulvérisation et d'ionisation par pulvérisation ionique.

Title: System for automatically routing calls to call center agents in an agent surplus condition based on agent occupancy
Inventor: FISHER THOMAS S
IPC: H04M3/523
Filed: 2000-11-22
Abstract: The system for automatically routing calls to call center agents in an agent surplus condition provides the call center administrator with an automatic agent assignment paradigm which functions to automatically increase the efficiency of assigning multiple skill agents to contacts. The presence of an agent surplus condition provides the present system with a plurality of choices in the assignment of the agent to process a presently received contact. Since the agents who staff the call center include multiple skill agents, the system must make a determination of not only which of the available agents is the best equipped to handle the present contact, but also how that assignment statistically effects the, efficiency of successive assignments of agents to contacts next received, based upon the past performance of the agents and the call center. Since the traffic load presented to the call center tends to be highly variable and of content that is difficult to predict, the present system provides several automatic agent assignment paradigms that each have a statistically different impact on the performance of the call center, based upon the quality and quantity of the incoming calls.

Title: Oligonucleotide primers that destabilize non-specific duplex formation and uses thereof
Inventor: PELLETIER JERRY
IPC: C12Q1/68
Filed: 1999-10-06
Abstract: The present invention relates to the demonstration that a modification of a homopolymeric stretch in an oligonucleotide, or primer, improves the discrimination for binding of such a modified oligonucleotide or primer to its complementary homopolymeric target sequence, as compared to a non-homopolymeric sequence. More specifically, an oligo d(T) primer having two of the thymine bases substituted by 3-nitropyrrole were used in a poly A primed cDNA synthesis experiment to demonstrate an improvement in discrimination between the priming of cDNA synthesis from bona fide poly A sequence as compared to internal A-rich sequences. The present invention relates to modifications of homopolymeric sequences in oligos, decreasing the ridging bonding capacity, in general, since other modifications, such as an oligo d(T) primer substituted with 2' deoxyinosine was also shown to improve the discrimination between the binding to a bona fide poly A tail as compared to A-rich sequences. The present invention thus relates to universal primers which reduce mispriming during cDNA library construction, thereby increasing the proportion of cDNA clones having been primed from the bona fide 3' poly A  tail. The present invention further relates to the use of the discriminating oligonucleotides of the present invention in other methods such as mRNA  purification, PCR-based detection methods and sequencing.
